using Microsoft.Office.Core;
using PowerPoint = Microsoft.Office.Interop.PowerPoint;

namespace PowerPointAddIn
{
    public class AddInHelper
    {
        public void GetOwnerDetails()
        {
            PowerPoint.Application pptApplication = Globals.ThisAddIn.Application;
            PowerPoint.Presentation presentation = pptApplication.ActivePresentation;

            // 获取演示文稿所有者的姓名
            string ownerName = presentation.BuiltInDocumentProperties[PpDocumentPropertyType.ppPropertyAuthor].Value.ToString();

            // 获取演示文稿所有者的联系方式
            string ownerContact = presentation.BuiltInDocumentProperties[PpDocumentPropertyType.ppPropertyCompany].Value.ToString();

            // 在控制台输出所有者详细信息
            Console.WriteLine("Owner Name: " + ownerName);
            Console.WriteLine("Owner Contact: " + ownerContact);
        }
